The structure is such that, upon thevtnrn-V@ ing of the disc 15, in thedirection indicated by the arrows in Fig. Land in Fig. 1, the p a te 9will be shifted longitudinally in the direction indicated by thearrow'vl9, so as to be moved directly rearwardly ofthe plate 8 andtheplate f8 buckligsuiciently topermit-its movement.

that, as the plates are buckled te produce the v curved-effect at' thecenterthereof, which.V is
